simon_tatham added a comment.

For this kind of pure refactoring on a `.td` file, my usual approach to testing 
it is to run the file through Tablegen without any output option (i.e. just in 
the default `-print-records` mode), before and after the change. In this case, 
I'd think, you ought to be able to expect bit-for-bit identical output – and if 
you get it, then you can be pretty confident that all the directly useful 
output modes won't have changed either.
